太原市部分地区排水中基本控制项目的检测及评价

Measurement and evaluation of basic control project the drainage in Taiyuan City

通过对太原市部分地区排水中基本控制项目(COD、氨氮、总氮、总磷、挥发酚及总有机碳)的检测,了解和评价太原市排水中的污染状况。用分光光度法测定氨氮,总氮,总磷及挥发酚,用高温燃烧氧化法测总有机碳。研究结果表明:太原市大部分地区排水符合标准,北沙河排水中的有机污染物较为严重,需要进一步改进。

To study and evaluate the current levels of basic control project(COD,ammonia nitrogen,total nitrogen,total phosphorus,volatile Penol and total organic carbon)in drainage in Taiyuan city.Ammonia nitrogen,total nitrogen,total phosphorus and volatile Penol in drainage were determined by spectrophotometric method and total organic carbon was determined by hightemperature burning and oxidation processs.The research results indicate that it is standard in drainage in most of taiyuan city,while organic pollutants is relatively serious in drainage in north river,need to be further improved.
